Application iiletl April 28, 1904. Serial No. 205,290.

To (LU who/1L [t 71mg coloc/Brit:

Be it known that I, lViLnnr. l. Surru, a citizen ot' the United States, and a resident ot' Denver, in the county ot' `Denver and State ot' Oolorado, have invented a new and Improved Railway-Switch, ot' which the following' is a full, clear, and exact description.

This invention relates to improvements in switches .for street-railways, an object being' to provide a switch mechanism of novel construction adapted to be operated by a motorman on a car while the car is moving'.

Al will describe a railway-switch embodying' my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying' drawings, forming' a part of this specilication, in which similar characters of reference indicate corresponding' parts in all the ligures.

Figure 1 is a plan showing' a switch mechanism embodying' my invention. Fig'. 2 is a section on the line ,1f a' of Fig'. 1. Fig. is a section on the line 1/ 1/ of Fig'. l. Fig. i is a perspective view, partly in section, o't` the shifting' mechanism; and Fig'. 5 is a plan showing a slight modilication in the shifting'- plate.

Referring' to the drawings, l designates a boxing' arrang'ed between rails Q 3 and below the sui-tace ot' the road-bed. The boxing' is provided with a cover si, on which a shittingplate is mounted to slide. On the upper side ot' the cover and at the ends of the plate 5 are cast ribs 6, and attached to these ribs 6 and extended Vt'reely over the plate isashort rail T, from which a tapered rail 8 extends forward. At its opposite sides the plate has upwardlyextended and longitudinallycurved ribs E). These ribs, however, need not necessarily be curved, but may be straight at the inner sides, as indicated at l0 in Fig. 5. Vln both instances, however, the ribs are divergent from the rear to the t'ront end. The opposite edg'es otl the plate are sharpened, so that when sliding' on the cover 4C any ice or snow that may be thereon will be readily c ut by the sliding plate. The ends may also be sharpened. To provide for easy movement o'tI the shitting-plate on the cover, the engaging surfaces ot' the two parts will preferably be smoothly planed.

A bolt l1, attached to the plate 5, extends into the boxing l, and the coveret is provided with a slot '12, in which the bolt may slide. Extended through the opening in the head ot' the bolt is a shitting-rod 13, and between the head ot' the bolt and collars lat 15 on the rod are springs '16 1T, which permit ol' slight yielding' movement ot the rod should the switch-tongue operated by the rod become clog'g'ed or meet with an obstruction or in case of a short throw ot the switch-tongue. An angle-arm '1S has pivotal connection with the rod i3 and extends through a stufiing-box in the end ot` the boxing l and is connected to theswitch-tongue l). The cover lis provided with an opening' through which the arm or railS maybe passedinto position. Thisopening', however, is normally closed by a cover Q0, which, as here shown, is seated on a gasket 2l, ot' rubber or the like, to prevent the Ventrance of water.

The switch-tongue is designed to be shifted, by means ot' the plate 5, tlu'ough the medium ot' a device carried by a car. As here shown, this device consistsot' rollers QQ 23, carried in a swinging' `trame 2i and desig'ned to engage between the rail T and one ot' the flanges. This feature, however, need not be fully described herein, as it forms the subject-matter ot' another application.

Having thus described my invention, I claim as new and desire to secure by Letters Patent l. Vln a switch mechanism, a switch-tongue, a shit'ting'- rod having' connection with the tongue, a sliding plate having' connection with the rod, divergent ribs on said sliding' plate, collars on the rod, and springs arranged between said collars and the connection between the rod and the sliding' plate.

Q. ln a switch mechanism, a switch-tongue, a boxing' arranged between the track-rails and having a slot through its top, a rod arranged in the boxing and having' connection with the switch-tongue, a plate mounted to slide on the boxing' and having' connection with said rod, and divergent ribs ou opposite sides of said sliding' plate, the edges ot' said plate being' sharpened.

ln a switch mechanism, a switch-tongue, a boxing' arranged between the track-rails, a shifting-rod in said boxing', an anglearm con- IOO necting said rod to the switch-tongue, a shifting-plate mounted to slide on the boxing and having connection with said rod,and upwardlyextended divergent ribs on said sliding plate.

4. In a switch mechanism, a switch-tongue, a boxing arranged between the track-rails, a shifting-rod in said boxing and having connection with the tongue, a plate mounted to slide on the boxing and having connection with said rod, upwardly-extended ribs at the opposite sides of said sliding plate, and a rail extended over the plate between the ribs and extending forward therefrom.

5. In a switch mechanism, a switch-tongue, a boxing arranged between the track-rails, a rod in said boxing and having connection with the tongue, longitudinally-extended ribs on the top of said boxing near the front and rear edges thereof, a shifting-plate mounted to slide on the boxing between said ribs, di-

vergent ribs at opposite sides of said sliding plate, and a rail attached to said first-named ribs and extended over the sliding plate be `VVILBER K. SMITH.
